Answer:
Li(s) + H20(l) --> LiOH(aq) + H(g)
Explanation:
it is already balanced
C. Diffusion is not a phase change.
The type of chemical reaction that the reactants will undergo would be a single displacement reaction.
In a single displacement reaction, one element gets substituted or replaced by another element in a compound. This often leads to the formation of a new compound (aqueous) and a new element (solid or precipitate).
Thus, the complete equation of the reaction becomes:
![Cu + 2AgNO_3 ---> Cu (NO_3)_2 + 2Ag](https://tex.z-dn.net/?f=Cu%20%2B%202AgNO_3%20---%3E%20Cu%20%28NO_3%29_2%20%2B%202Ag)
Cu displaced Ag from AgNO3. Thus Ag becomes precipitated in solution while a new compound, CU(NO3)2 is formed.

What is the element with 7 protons? They probably also have 7 neutrons. Just a ball park figure guess.
